Chapter 1 Introduction This Chapter. . . p provides a physical description of the switches, indicators and connectors on the rear panel of the T5 Enclosure.
Equipment Description The Tape Array (T5) Rackmount Enclosure can house from one to five Quantum® DLT7000 or DLT8000 SCSI tape drives in a well-integrated package for use in rackmount applications. Included on the rear panel of the T5, 10 HD68 SCSI connectors allow separate SCSI bus connections to each drive. Five drive SCSI ID selection switches are also included on the rear panel.
Rear Panel Connectors, Switches and Indicators Drive SCSI ID Switches AC Power Connector PS Status Indicators Power Switch SCSI I/O Connectors Figure 1-2: T5 Rear Panel Rear Panel Connectors, Switches and Indicators Power Switch Turns on AC power to the T5 Enclosure. AC Power Connector Plug the T5 Enclosure AC power cord into this connector.
Power Supplies Two redundant hot-swappable 300-watt power supplies provide operating voltages for the DLT tape drives installed in the T5 Enclosure. The two supplies operate in parallel using proprietary power control and sharing modules. Each supply plugs into the rear of the T5 and can be removed or replaced while the other supply keeps the system fully operational.
Cooling The T5 enclosure is cooled by four fans, two of which are contained in the power supply modules and whose status is reflected by the power supply status indicators. The other two fans are mounted on the chassis rear panel and are easily removed and replaced while the system remains in operation.

Each shipping carton should contain the following: • A T5 Enclosure chassis with two removable power supply assemblies and internal SCSI data cables, as ordered.
Installing SCSI Cables, Jumpers, and Terminators Follow the steps on the following pages to connect your T5 to one or more SCSI busses. This involves installing SCSI cables, jumpers (daisy chain cables), and terminator(s) onto the SCSI I/O connectors on the rear panel of the T5. Note The interface cable(s) must be shielded – ADIC can supply you with the correct type(s). The T5 Enclosure can contain up to five SCSI DLT tape drives.
SCSI Terminators External SCSI bus terminators should be used with either single-ended or differential drive configurations. 1. Install any required external terminator(s) on the appropriate SCSI connector(s) on the rear panel of your T5 Enclosure. Note A drive should only be terminated if it is the last physical device on a SCSI bus. SCSI ID Selection Switches The SCSI ID selection switches are located at the top, near the center of the T5 rear panel.
